Effect of Irrigation and Fertigation Regimes on Growth and Yield

The study reveals drip fertigated chilli cultivation to be profitable under white and green+white shadenet with daily drip irrigation @ 1.0 ETc and fertigation @ 140% RDF. The experimental result will be useful to the farmers engaged in chilli cultivation under semi-arid conditions.

Effects of Aerated Drip Irrigation on the Soil Nitrogen

Currently, the most widely used irrigation technology is subsurface drip irrigation (SDI), which can significantly improve water and fertilizer utilization efficiency and achieve precise irrigation and fertilization in the root zone [1, 2, 3].

Drip Irrigation for Chili Peppers

Irritec® fertigation systems combine practicality and reliability with a modern nutrient injection system. Fertiliser management is regulated by simple fertigation recipes that can be set according to agronomic and nutritional requirements.

Fertigation Methods and N Source on Chili through Drip Irrigation

Research objectives were to find out the best fertilizer application methods through drip irrigation and obtain a nitrogen fertilizer source that can increase polyethylene mulched chili yield.

Chili pepper drip irrigation fertigation is a modern agricultural technology that delivers fertilizers directly to the root zone of crops in water soluble form, enabling precise nutrient application. This method significantly improves fertilizer use efficiency, reduces environmental pollution, conserves water resources, and allows flexible adjustment of fertilizer dosage and concentration based on crop growth demands and soil conditions.

Methods for Concentration Control

1. Determine Nutrient Requirements of Target Crops

Before applying drip irrigation fertigation to chili peppers, it is essential to understand the crop’s growth cycle, stages, and nutrient needs (e.g., nitrogen, phosphorus, potassium). This can be achieved by referencing agricultural guidelines, conducting soil tests, or consulting professional agronomists.

2. Select Appropriate Fertilizer Types

Choose fertilizers tailored to chili pepper growth phases. For example, use urea for high-nitrogen periods, superphosphate for high-phosphorus stages, and potassium sulfate for high-potassium requirements.

3. Calculate Fertilizer Dosage

Based on soil test results and crop nutrient demands, calculate the total fertilizer weight needed. Then, determine the dosage per irrigation using drip system parameters. For instance, if 50 kg/ha of fertilizer is required, the dosage per irrigation would be ( 50 , ext{kg/ha} imes 500 , ext{m/ha} = 25,000 , ext{kg} ).

4. Adjust Fertilizer Concentration

Due to the high flow rate in drip systems, fertilizers must be dissolved in water to create a uniform solution. The optimal concentration is typically provided by manufacturers or determined experimentally. Adjust the water-to-fertilizer ratio during irrigation to maintain desired levels.

5. Monitor and Adjust

Regularly test soil nutrients and observe crop health to refine fertigation plans. For example, reduce nitrogen if soil levels are excessive or increase specific nutrients if deficiency symptoms arise.

6. Use Specialized Equipment

Employ dedicated fertigation devices with automated flow and pressure control to ensure accurate, consistent nutrient delivery. These tools adapt to crop needs and soil conditions in real time.

7. Train Operational Staff

Operators must be trained in drip system mechanics, fertigation techniques, and troubleshooting. Proper training ensures alignment of practices with crop and soil requirements.

8. Follow Safety Protocols

Adhere to safety standards, such as avoiding direct fertilizer intake into water sources, maintaining system integrity, and using personal protective equipment (PPE) to prevent exposure to hazardous substances.

controlling fertigation concentration for chili peppers requires integrating crop nutrient needs, fertilizer properties, system design, and operator expertise. Scientific methods and technologies enable precise nutrient management, enhancing fertilizer efficiency and promoting healthy crop growth.
